NONSKID ATTACHMENT FOE VEHICLE WHEELS.

Application filed November 19, 1921. Serial No. 516,290.

To all whom it may concern:

Be it known that I, GEORGE F. HOGAN, a citizen of the United States, ,residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Nonskid Attachments for Vehicle Wheels; and I do hereby declare the following to be a .full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in nonskid attachments, and relates particularly to a construction, wherein the functions of nonskid devices and tire armor are combined. Non-skid attachments are of two types, namely those whose only function is to assist traction, and those which combine this function' with that of protecting the tire from external injury. In the former class are tire chains. Such devices are in the form of flexible nets of wide mesh, which expose large areas of th tire to the road surface.

They afford no protection for the tire, and

are liable of themselves to injure the tire. The latter are expensive, unsightly, troublesome to apply and remove, and materially impair the normal cushioning function of the tire.

The object of the present invention is to provide a simple, inexpensive attachment of the character specified, which may be easily applied to the tire and which while materially supplementing the traction of the tire, will at the same timeaiford suflicient protection against external injury without in any manner impairing the reslliency of the tire. r

- In the drawings;

shown, the attachment is a strip 1 of flexible material, as for instance heavy canvas, of a length to extend circumferentially ofthe side edge of the strip.

the. embodiment of the invention tire 2 of the wheel 3 upon which it is to be placed, and tolap at its ends. Preferably the ends of the strip are crimped as shown at 41, to cause the said ends to closely engage, to prevent entrance of foreign bodies between the strip and the tire. By thus crimping the overlapping ends of the strip and causing them to closely engage the surface of the tire, the ends are made more rigid and the fastening means, to be later described, is assisted in preventing the rolling up of the end of the outside overlapping margin,

which is the-natural tendency of two overlapping surfaces positioned in this manner on the outside of a vehicle tire. The strip is of a width to cover the tread, and to ex tend well beyond the same on each side, and series of headed traction studs to be later described, are connected with the strip. The studs 5 as shown more particularly in Figure 4 have roughened engaging faces, and each stud has a shank 6 which passes through an opening in the strip 1, and through a washer 7 on the opposite side of the strip, and the shank is upset at the washer, to practice the studs are discs, which are approximately one and three-quarter inches in diameter, and about one-half inch in height,

hold the stud to the strip. In

that is in extension beyond the face of the strip. The studs are preferably arranged as shown in Figures 1 and 5, in lines extending diagonally of: the strip. In the present instance there are three studs in each line or series, and the members of the series may be in alinement longitudinally of the strip with corresponding members of the other series, or they may be arranged in staggered relation. A second strip 8 of suitable material is vulcanized to that face of the strip 1 adjacent to the washers 7, covering suc washers, and preventing injury of the tire 2 by the washers and the shanks of the studs. The strip 8 also limits movement of the studs with respect to the strip 1. Each is provided with a number of eyelets 9, and the e elets are designed. for engagement by hol ing means to hold the strip to the tire.

Any suitable form of holding means may be used. In the present instance, such means is in the form of yokes, each comprising a'. I

body 10 and of each yoke has an eye 13 which engages an eyelet 9 of the strip. The other arm 12 of arms 11 and 12. The arm 11 each yoke has a similar eye lfi, to which is f strip, and to be swung down upon the arm 12 s shown. The elbow lever is held from displacement by means of a spring clamp 16 mounted to slide on the arm'12 of theyoke. This clamp as shown in Figures 2 and 3 has spring lugs 17 which engage about the adjacent arm of the lever 15 and the arm 12 of the yoke, locking the lever 15 in operative position against the yoke arm. In securing the clamp in place the clamping lever is pressed by the fingers-firmly against the arm 12 of the yoke which causes the spring lugs 17 to be sprung outwardly. As their ends pass over the surface of the arm, they spring toward each other, engaging the arm 12 to lock the lever 16 in the fina operative position. To release the yoke,- the clamping lever 16 is swung outward. This releases the elbow lever 15, which may be swung'up and out, and slipped through the eyelet 9. The yokes may be arranged at suitable intervals, as for instance between the alternate pairs of spokes, or between each pair of adjacent spokes as shown. In placing the improved attachment, the strip is laid in front of the wheel to which it is to be applied, with the studs 5 downward, and the wheel is run upon the strip. The strip is now lapped at its ends about the wheel and the holding yokes 10 are operated to connect the side edges, of the strip. As shown the strip is of a width such that when in place it will extend radially inward at each side edge beyond the rim of the wheel. The attachment is flexible, conforming closely-and easily to each change in the shape of the tire, and in no way impairing the normal function of the tire. There is nothing in the construction of the attachment which might injure the tire, the studs being prevented from direct engagement withthe tire by the facing strip 8, and the attachmentis in itself a protection for the tire against injury by foreign bodies. While forming a complete covering* and armor for the tire, it is of suchnature that the tire may function perfectly without interference on the part of the attachment.

In Figures 6 and 7 there is shown an alternate form of clamping means. The said means is in the form of flexible strips 18 of metal, which are arranged at suitable intervals between the strips 19 and 20 which constitute the attachment, corresponding to the strips 1 and 8 of Figure 1. One end of each strip 18 is provided with an eye 21, and

the other end with a pivoted elbow lever 22, similar to the lever 15, andoperating in the same manner. The lever 22 is held in look- 'ing position, by a loop 23 mounted to slide on that end of the strip 18 to which the lever 22 is pivoted. In thisconstruction, the strip 18 is of a length to extend entirely side edge,

around the tire and the felly of the wheel, and the strip 1 is relieved from the pull of the holding means.
